In the 9 months I've had mine, they've probably increased in size 20 fold. Seems like every 2 weeks now, I'm fragging 3-4 pcs and taking them to either of 2 local
LFS. 6 days with a rubber band and they taken to the new rock already. They are in mild, moderate, and kinda heavy flow areas and doing well in all places. I've even seen small, single polyps on rocks in the lower part of my tank. Uh, oh. I've even cut one - like a hair cut, and left some "jelly
frag" on a rock - as opposed to slicing a branch off. Now I've got a mini "afro" xenia growing, 1/2 inch tall. There's no stopping that stuff.
Borneman notes that there is prolific growth of xenia and other family members around the effluent discharge of hotels and sewage pipes on near shore reefs. Hmmm...
Got PCs w/twin 65w on 11 hrs. And the 65W blue (actinic, right?). Not dosing a lot either.
